Proto J6202A Torque Wrench Multiplier 750 Ft/lb 3/4 in Drive

Product Description

The PROTO J6202A is a single-stage torque wrench multiplier designed for high-torque fastening applications where standard torque wrenches cannot deliver sufficient output. It accepts a 3/4 inch drive and produces a maximum output of 750 ft/lb through a 3.3:1 gear ratio with a 3.33:1 effective multiplier ratio. The head measures 2.8 inches in diameter and 3.1 inches in thickness, keeping the profile compact enough for confined work areas. Weighing 4.77 pounds, it is built for field use by mechanics, millwrights, pipefitters, and maintenance technicians who regularly work with large-diameter fasteners on heavy equipment.

The J6202A is suited for industrial maintenance, heavy equipment service, pipeline work, and structural assembly where precise high-torque application is required. Single-stage gear systems like this are common in applications involving large flange bolts, equipment anchor bolts, and heavy machinery fasteners. It is appropriate for both shop and field environments where a torque multiplier is needed to extend the practical range of a standard torque wrench input.

Key Features

• 3/4 inch drive output for compatibility with standard heavy-duty sockets
• 750 ft/lb maximum output torque capacity
• 3.3:1 gear ratio with 3.33:1 effective multiplier ratio for accurate torque scaling
• Single-stage gear system for straightforward operation and reduced mechanical complexity
• Compact head profile at 2.8 inches diameter and 3.1 inches thickness for use in tight spaces
• 4.77 pound field-portable weight suitable for on-site maintenance work

Compatibility

Designed for use with 3/4 inch drive torque wrenches and sockets in industrial and heavy-duty mechanical service applications.

Installation Notes

Torque multipliers are typically used by licensed mechanics, millwrights, or industrial maintenance technicians following equipment manufacturer torque specifications. Ensure the reaction arm is properly secured against a stable surface before applying torque to prevent tool movement or injury. Verify that the input torque wrench is calibrated and within its rated range before use. Follow applicable workplace safety standards and equipment service manuals for fastener torque requirements.
